Reasons Your Roof Shingles Are Curling
Even though roofing shingles protect your household from the weather, sometimes they can be the culprits behind your roofing troubles. Shingles can loosen or curl for various reasons, leaving your roof inefficient and unpleasant to look at. Other results of curled shingles include leaks and structural damage to your home. Therefore if you notice that your shingles have begun to curl, you should have your roof inspected by a qualified roofer to determine whether your roof should be repaired or replaced. Below are four reasons why roof shingles curl:
An Improperly Ventilated Attic
A well-ventilated roof has intake vents on the lower and upper parts of the roof. Therefore, the ventilation system of your roofing system is able to pull outside air via the lower intake vents and then expel it to higher areas of your roof. This process helps prevent heat from getting trapped in the attic of your roofing system and helps prevent moisture buildup, which could otherwise lead to additional problems such as mold. If the roof's ventilation is ineffective, it means that heat will build up in your attic and so causing your shingles to curl. Besides addressing the issue of the curled shingles, a roofing contractor also needs to sort out the ventilation issue to help prevent the problem from recurring.
Poor Shingle Installation
If non-professionals did your shingle installation, it might have been done without following the necessary guidelines, including the type and number of nails for each shingle, underlayment specifications, etc. In addition, new shingles may have been installed over old ones. Though it saves time and money, this technique is often discouraged because it has some downsides. For instance, it leads to an overly heavy roof and can cause the new shingles to curl prematurely if the old roof had problems.
Your Shingles Have Reached Their Maximum Lifespan
Roof shingles can also start curling if they are too old. Instead of waiting for your shingles to deteriorate completely, it is usually advisable to replace them as they approach old age. Apart from curling, you can tell that your shingles are approaching their end if you see granules in the gutters or if some of the shingles are missing.
Use of Defective Shingles
Shingles can curl soon after they have been installed if they are defective. Such defects may occur at the manufacturing stage. This is why you should preserve your warranty documents to make a claim for replacement in case of a defect. Additionally, roof inspections help you be aware of this and similar problems in good time.
Curled or cupped shingles are usually noticeable from the ground level. Since such shingles rarely do a proper job, you cannot afford to ignore this issue. For this reason, look for an expert professional roofer to diagnose and resolve the situation. Once they find out why the shingles are curled up, they will determine the appropriate action to take.
